5. Connecting Loads  

You will want to be careful when connecting loads so as not to overload the generator, especially if 
you are powering devices with motors that require a higher starting power load. 

 

Instructions are provided below for connecting loads when you are using the generator: 

 

As a portable power source 

Connected to a building as a back-up power source

  

 

       

WARNING

:   

Do not overload generator.  Make sure that combined starting and running loads do 
not exceed rated capacity of generator.  Overloading the generator can cause damage 
to the generator and attached electrical devices, and may result in fire.

 

 

Using as a  
Portable Power 
Source

 

Connect electrical loads one at a time according to the following 
instructions: 

 

1.  Allow engine to reach operating speed by allowing it to warm up for 

approximately 5 minutes before connecting electrical devices. 

 

2.  After engine is warmed up, begin by connecting the items that require 

the highest wattage first.  The recommended sequence is as follows:   

 

a. Connect items with motors such as refrigerators, freezers, air 

conditioners, or small hand tools, one at a time.  Let each motor 
stabilize before connecting the next device. 

 

b. Connect any lights you are planning on powering.   

 

c. Connect voltage sensitive equipment such as electronics via surge 

protectors.  Plug devices such as TV’s, computers, and microwaves 
into a UL listed voltage surge protector, then plug the surge 
protector into the generator. 

Using as a  
Back-up Power 
Source for a 
Building 

Each transfer switch installation will be unique.  

 

Proper instructions for how to safely bring the generator online with the 
building’s electrical system should be provided by the installing electrician, 
who should also provide personal instruction to the owner/operator.   

 

Failure to follow the proper procedure as provided by the electrician could 
expose persons to the hazards noted above.   

 

6. Stopping 

Stop the engine using the following steps: 

 

1.  Disconnect all loads to the generator. 

2.  Turn engine key switch to OFF position. 

3.  Turn gasoline line shut-off valve to OFF position. 

4.  Remove key from starter to prevent accidental starting of engine.
